MACHINE FOR SCRAPING THE QUILL'S OF FEATHERS.

SPECIFICATION forming part of Letters Patent No.'347,486, dated August1'7, 1886.

Application filed October 23, 1885. Serial No. 180,782. (No model.)

To all whom it may concern.-

Be it known that I. JOHN HAwLowETz, of the city, county, and State ofNew York,'have invented certain new and usefullmprovements in Machinesfor Scraping the Quills of Feathers, of which the following is aspecification.

The object of this invention is to furnish a machine by which the quillsof feathers to be used for feather trimmings and other purposes may bequickly and uniformly scraped and reduced to a uniform thickness, andthe slicing of the quills by cutting-knives is dispensed with; and theinvention consists of a machine for scraping the quills of feathers,formed of a chamber having a slotted top opening and a rotatingscrapingroller projecting through said opening. The chamber is connectedby a channel to a suction-fan for drawing off the dust, while a guard isattached to the top of the chamber and extended partly over thescraping-roller.

In the accompanying drawings, Figure 1 represents a verticallongitudinal section of my improved machine for scraping the quills offeathers. Fig. 2 is a plan of the same with the top plate removed. Fig.3 is aplan, with part of the top plate broken of, of a modifiedconstruction of my scraping-machine. Fig. 4. is a vertical transversesection on line as m, Fig. 3.

Similar letters of reference indicate 'corresponding parts.

Referring to the drawings, A represents a chamber, which is made of woodor other suitable material, and provided in its top plate with a slottedopening, a, through which an abrading roller or wheel, B, projects. Thechamber A is providedwith journalbearings b b for the axle b of anabrading wheel or roller, B, which receives rotary motion by anysuitable transmission. The chamber A is supported by suitable standardsat such a distance from the floor that a girl or other attendant can sitsidewise of the machine and hold the feathers in proper position towardthe abrading-roller. The abradingroller B is made of wood orothersuitable mate rial and covered with sand-paper, ground glass,

. or other equivalent abrasive material glued thereto. Two abradingwheels orv rollers B are preferably arranged on the same axle,- with apulley, b between the same, as shown in Figs. 1 and 2, in which caserotary motion is transmitted from the driving-shaft by a belt to thepulley b on the axle of the wheels. Two chambers A A are in this casearranged parallel to each other, and the axle of the abradingrollers Bsupported in journalbearings b of the adjoining walls of the chambers AA. A series of pairs of abrading wheels or rollers may be arranged inline, in which case the chambers A are extended. to the length requiredby the rollers, as shown in Fig. 2. The chambers A are connected bychannels A, which are arranged at suitable intervals between theabrading-rollers with a suctionfan, by which the dust caused by theabrading action of the wheels on the quills is drawn off and conductedto the outside of the building within which the scraping-machines arelocated. A guard or hood, 0, extends over a part of the abrading-wheelB, and

serves as a rest for one hand while exposing the quills to the action ofthe abradingrollers, and as a protection against injury to the hand.

In Figs. 3 and 4 a modification of my im proved machine for scraping thequills of feathers is shown, in which the scraping wheels or rollers arearranged in a circle, in stead of in line with each other, as in Figs. 1

and 2, and in this case motion is transmitted I to the action of theabrading-wheels by a rotating disk, E, and friction-rollers, E, whichare splined to the axles b b, so as to slide thereon, but rotate axiallytherewith. The friction-rollers E on the axles I) b of theabrading-wheels B B are thrown in contact with the motion-transmittingdisk E by fulcrumed bell-crank levers 0, provided with a treadle, e, atthe lower end and a fork, 6", at the upper end, the fork engaging agrooved collar, f, on the shaft of the friction-roller, so as to shiftthe latter on the axle against the tension of an interposed spiralspring, f, away from the transmitting-disk E when the treadle isdepressed, and into contact with the same, so as to rotate theabrading-wheels when the treadle is released. The chambers A areseparated by radial partitions and are connected by channels D with acentral receiver, D, which latter is connected by a pipe, D to thesuction-fan, so that the dust is drawn off and conducted through thechimney to the outside.

In operating the machine, the quills of the feathers are taken hold ofby both hands at the butts and tips, one hand resting on the guard D,and exposed to the abrading action of the roller, first at one side andthen at the other side. While the action of the wheel takes place thefeather is moved in lougitudinal direction over the roller, so that thequill is abraded in part or entirely at one side, after which thefeather is turned and the other side exposed to the abrading action ofthe roller in the same manner. The fines are forced away from the wheelduring the scrap ing action by the motion imparted to the air by therapid rotation of the scraping-roller, so that the fines are not injuredor scraped off. The dust is carried along by the rapidly-r0- tatingscraping-wheel and deposited in the inclosing-chamber and sucked off bythe fan. The quills of feathers of all kinds are thus scraped off touniform thickness in a quick and convenient manner without injury to thelines, whereby the feathers are better adapted to be woven intotrinnnings or other textile fabrics.

I am aware that scraping and abrading machines have been provided withsuction devices for carrying off the dust, 800., and I do not claim,broadly, machines of this class. The machines of this kind usedheretofore have not been provided with curved guards or hand-rests solocated as to extend partly over the projecting top part and above thehighest point of said top part of the abradine wheel or disk, whichlatter is rotated toward the guard, whereby all the dust ground from thequills is carried below the guard into the chamber and then carried offby the suction device. This is an essential feature of my machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, with a chamber connected with asuction apparatus, of a rotary abrading-disk extending through a slot inthe top of the chamber, and of a curved guard extending part-1y over therim of the disk, the highest point ofthe guard being above the highestpoint of the rim of the disk, subslau' tially as herein shown anddescribed.

2. The combination, with a chamber connected with a suction apparatus,of a rotary disk or wheel, and a curved guard cxtem'ling partly over thetop part of the rim of the disk, said disk being rotated toward theguard, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
